Are you building your code using the OpenAMQ build system ('c' and
friends) or not?

If not, then you need to make sure that you're defining the exact same
set of flags when *compiling* your code as are those that 'c' defines
for your build model.  You can get those out of 'c' by e.g.:

1. Go to .../OpenAMQ-1.2c4/clients
2. Run "c -v -l amq_client"

Specifically for multi threaded builds, it is not sufficient to just
define -D_REENTRANT.  You need at least -DBASE_THREADSAFE and
-D_LARGEFILE64_SOURCE as well.
